- the electrode structure in which the wiring 43 is formed on the outer surface of the glass substrate is employed, it is possible to connect a plurality of panels as shown in FIGS. 9 and 10 to constitute an ultra-large display system.
- a plurality of panels can be driven by a single drive circuit.
- the advantages are as follows. First, the circuit cost is reduced. The second is the power of image continuity between panels.
- the sustain electrodes are connected even if there are multiple panels, they can be regarded as one electrode, so there is no variation in luminance due to the difference in display load. For this reason, even if an ultra-large display system is configured, the display quality is good because the continuity of the video is good.
- each panel is driven by an independent drive circuit, so each panel can be displayed even if one image is displayed on each panel.
- the load of the video that is in charge of is different and the expression of brightness and gradation is inconsistent.
- the panel load is different, so the APC point that adjusts the panel power 'brightness' is shifted, which causes the drive frequency to be different.
- the result is that the continuity of line brightness cannot be maintained.
- a low-cost, low-resistance display electrode, a low-reflectance panel, and a super-large panel can be realized.
